Hello, I couldn't seem to find a better place for this question, if there is a better one, please feel free to shift it there.
I have 4 photos from 1971, and if I hover the computer mouse over them, a date of 3/6/1971 comes up as well as a time for each. My question, can these be correct shooting times? I Googled all this sort of thing, trying to find when this information was first available, but I guess since my knowledge of these things is limited, I found nothing. Any information on this would be appreciated.
Thank you,
